In short, when someone sets my site to French and goes to checkout and is selecting shipping method, the expedited option does not work. If someone selects expedited, it loops the person back to the shipping page and will sometimes even add a few bucks to the shipping cost.

Standard shipping works fine in French, and expedited works fine in English, so I'm a little confused as to what the problem might be. Could the accents in "Colis accéléré" (Expedited) be causing the problem? It's the only shipping method I have with accents.

Any help would be appreciated.
